JOHN HARLEY, OF WALLACEBURG, ONTARIO, CANADA, ASSIGNOR TO HIM- SELF AND JOHN B. NEWMAN, OF SAME PLAGE.

SASH-FASTENER.l

SPECIFICATION formingpart of Letters Patent No. 232,710, dated September 28, 1880.

To all whom it may concern:

Beit known that I, JOHN HARLEY, of Wallaceburg, in the Province of Ontario and Dominion of Canada, have invented a new and Improved Sash Holder and Fastener, of which the following is a specication.

The object of my. invention is to provide a new and improved sash. holder and fastener, which is simple in construction and eiiective in use.

In the accompanying drawings, Figure l is afront elevation of' a corner of a sash provided with wmy improved sash holder and fastener Fig. 2 is a cross-sectional elevation of the said sash on the line x Fig. l. Fig. 3 is a horizontal sectional view of the sash on the line y y, Fig. 1. Fig. 4 represents inside elevations of the wedge-shaped slide and casing.

Similar letters ot' reference indicate correspending parts.

A wedge-shaped slide, A, is provided with a handle, B, and with a laterally projecting ilange, C, at the upper end, and a like llange, D, at the lower end, the lower end being also provided with a hook or lug, E, for a purpose described hereinafter.

The straight edge of the slide A is provided with a recess, F, which tapers from the lower iiange, D, toward the upper flange, O.

The beveled side of the slide A is provided with a curved notch, Gr, to receive the end of a rubber spring, H, which is held in a curved groove, I, in a casin g, J, provided with a wedgeshaped recess, K, to receive the slide A.

The casing J is attached to the windowframe L in such a manner that the lower edge of the liange C of the slide A which has been passed into the casing is about on a level with the upper edge of the upper transverse rail, M, ofthe lower sash.

The flanges U and D may project toward the center of the sash, as shown, or they may project toward the edge of the same; but in the latter case the groove in which the sash slides will have to be enlarged to permit the larges to enter between the end railv of the sash and the strip of the casing-L.

Application filed July 22, 1880. (Model.) Patented in Canada J une 19, 1880.

The device operates as follows: By raising the sash the slide A is drawn out of the wedgeshaped recess K in the casing J, and does not interfere with the opening ot the window; but as soon as the sash is released the friction between the end rail of the sash and the surfaces of the iianges O and D, pressed against said rail by the spring H, is sufficient to press the wedge-shaped slide A into the recess K; but as the slide A descends the pressure upon the sash increases proportionally, and the sash is thus held.

lf the sash is to be lowered, the slide A is raised by means of the handle B, thereby releasing the sash from the pressure ofthe said slide; but as soon as the slide is released the sash is locked in the position it had at that moment.

If the sash is lowered and is to be locked,

the slide A is raised until the lower edge of the ange O is above the upper edge of the upper sash-rail, M, upon which the spring H presses the said liange over the said rail, as shown in Fig. 2, thereby locking the sash.

The lugI or hook E prevents the slide A from being raised higher than is necessary, and from being drawn out of the casing entirely.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a sash holder and fastener, the wedgeshaped slide A, constructed, substantially as herein shown and described, with a handle, B, hook E, a tapering recess, F, on the straight edge, and with lateral flanges O and D at the top and bottom, respectively, as set forth.

2. In a sash holder and fastener, the casing J, constructed, substantially as herein shown and described, with a wedgeshaped recess, K, and a curved groove, I, for holding a spring, H, as set forth.

JOHN HARLEY.
